Abstract :
The model explained above is simulated using Monte Carlo methods with a heat-bath algorithm and single-spin flipdynamics. The trial step for a spin update is a spin flip for the Ising model and a random choice of a spin vector for the Heisenberg model. We perform typically Monte Carlo steps per spin (MCS) for a calculated susceptibility and magnetization for one particular configuration of the defects.We have used the Monte Carlo simulation technique to investigate the temperature dependence of magnetization and susceptibility and effect of size in the curie temperature also investigated. The results are in a good agreement with experiment.
